Pure Maps

Latest release SFOS Ubuntu Touch Flatpak Fedora

Matrix TMO

Pure Maps is an application for Sailfish OS and Linux to display vector and raster maps, places, routes, and provide navigation instructions with a flexible selection of data and service providers.

Pure Maps is free software released under the GNU General Public License (GPL), see the file COPYING for details. Pure Maps is a fork of WhoGo Maps that was made to continue its development.

User feedback

There are three main communication channels with the users: GitHub, Matrix channel #pure-maps:matrix.org and a thread at TMO.

Please use Github issues to address specific problems and development requests. General discussion is expected either through corresponding issues, Matrix channel, or TMO thread. Please note that users from all platforms are welcome at TMO, not only current Sailfish OS users.

Currently, the homepage for Pure Maps is a placeholder. You are welcome to help by working on the corresponding issue.

Command line options

Pure Maps supports positional argument (one) that could either specify geo:latitude,longitude URI or a search string that will be searched by geocoder.

If Pure Maps instance is running already, it will be contacted via DBus and the request will be forwarded.

DBus API

DBus (service io.github.rinigus.PureMaps at session bus) can be used to

  • search: method Search
  • show poi: method ShowPoi
  • get navigation status and control it.

There service is split as described below.

Global actions

Path: /io/github/rinigus/PureMaps Interface: io.github.rinigus.PureMaps

Methods:

  • Search(String search_string) - activates search action for given search_string

  • ShowPoi(String title, Double latitude, Double longitude) - show POI on map with the given coordinates and title.

Navigation

Path: /io/github/rinigus/PureMaps/navigator Interface: io.github.rinigus.PureMaps.navigator

Methods:

  • Clear() - stops navigation and removes current route

  • Start() -> Boolean - start navigation and returns true if succesful. If already started or has no route defined, will return false to indicate failure.

  • Stop() - stop navigation if running.

Properties and signals:

Each property has a corresponding ...Changed signal to indicate when the value of the property has changed.

  • destDist, destEta, destTime - human readable strings with the remaining distance, time, and estimated time of arrival

  • direction and directionValid - bearing of the current route segment and whether it is valid (current location is on route)

  • hasRoute - whether route has been set in application

  • icon - icon name for the next maneuver

  • language - navigation instructions language

  • manDist, manTime - remaining distance and time for the next maneuver in human readable form

  • mode - mode of transportation

  • narrative - longer next maneuver instruction, should be available for all maneuvers

  • alongRoute - whether current location is on route and movement is along it.

  • progress - current progress along the route in percentage (0-100)

  • running - whether navigation in active

  • street - short form of the narrative usually shown in Pure Maps next to the maneuver icon. Could be absent for some maneuvers

  • totalDist, totalTime - total route distance and time in human readable form.

Development

For development of Pure Maps and testing on desktop, you would have to choose platform for which you develop, install dependencies, and be able to run the application. In this case, Qt Creator can be used. See details below.

Alternative, is to use Flatpak-based environment and develop using that. For this approach, see separate README.

Building and Debugging for Ubuntu Touch is described in README.

Platforms

To support multiple platforms, QML code is split into platform-specific and platform-independent parts. Platform-independent part is in qml folder with the platform-dependent code under qml/<platform-id>. Correct platform is picked up in installation phase (make install) or is set by make for local builds.

Within platform-independent code, platform is included allowing to access platform-specific implementations of page stack, file dialog, and other specific aspects. For this approach to work, API in the platform specific implementation has to be the same for all platforms.

To add new platform, add new directory under qml, new Makefile target to set it, and implement all the required QML items. Take a look under other platforms for examples.

Dependencies

In addition to common dependencies for QML applications, the following are needed:

When developing with Kirigami using flatpak builder, dependencies will be pulled and installed in flatpak. See instructions regarding Kirigami below.

GPXPy is also provided as a thirdparty submodule and can be installed together with Pure Maps by setting corresponding option during cmake configuration phase.

Building

Starting from Pure Maps version 2.0, the application has to be compiled. You could either

  • compile/install/run
  • compile/run from source tree

In the both cases, you would have to specify platform via -DFLAVOR to cmake. Supported platforms:

  • Kirigami: FLAVOR=kirigami
  • QtControls: FLAVOR=qtcontrols
  • Sailfish: FLAVOR=silica
  • Ubuntu Touch: FLAVOR=uuitk

It is recommended to build the sources in a separate folder, as in

mkdir build
cd build
cmake -DFLAVOR=kirigami ..
make && make install

For compile/install/run, use regular make and make install before running application.

To run from the source tree, add -DRUN_FROM_SOURCE=ON option when running cmake. Please note that, when running from source tree, do not run make install in the build folder. Otherwise it can overwrite your source files. In this case, make and running compiled executable directly would allow you to run application without installation. For example, from Qt Creator directly.

The build options can be specified in Qt Creator under "Build settings" of the project. Just add them to the additional arguments of cmake.

Mainly targeting packagers, it is possible to specify default providers using cmake project options. Notice the difference in supplied values for basemap and other options:

  • DEFAULT_PROFILE=profile where profile is either online or offline
  • DEFAULT_BASEMAP=provider Map provider is either specified in basemap JSON as "provider" or, if absent, as "name"
  • DEFAULT_GEOCODER=provider
  • DEFAULT_GUIDE=provider
  • DEFAULT_ROUTER=provider

In the last three options, provider corresponds to the basename of JSON/Python file describing the provider. Example: "photon".

API keys

Note that you will need API keys if you wish to access the services that require them (such as Mapbox). For that, register as a developer and insert these keys in the preferences. Among services that don't require API keys are OSM Scout Server (for offline maps), HSL (raster tiles for Finland), Sputnik (raster tiles in Russian), Photon (search).

Packaging

Pure Maps is packaged for different distributions. Included in the source tree: Sailfish OS version is packaged as RPM, Linux version is packaged using Flatpak or RPM, and Ubuntu Touch version as click. Several distributions provide packaging scripts in their source trees.

For packaging, please copy tools/apikeys_dummy.py to tools/apikeys.py and fill missing API keys for the services that you plan to use.

Flatpak specific instructions are available under packaging/flatpak.

Ubuntu Touch specific instructions are available in Ubuntu Touch README.

Development

General

Throughout QML, Python, and C++ code, all the same type items (properties, signals, functions), are ordered alphabetically.

Its possible that some of the implemented code does not fully comply with the outlined order. Then it should be fixed eventually.

QML

To simplify development, there are few simple rules regarding QML file organization. QML files are organized as follows (use the needed components):

import A
import B
import "."

import "js/util.js" as Util

Item {
    id: item

    // base class defined properties in alphabetic order
    prop_a: val_a
    prop_b: val_b

    // new properties in alphabetic order
    property         var  np_a: default_a
    default property bool np_b: default_b

    // readonly properties
    readonly property var images: QtObject {
        readonly property string pixel:         "pure-image-pixel"
        readonly property string poi:           "pure-image-poi"
        readonly property string poiBookmarked: "pure-image-poi-bookmarked"
    }

    // signals
    signal mySignal

    // local unexported properties
    property bool _locked: false

    // behavior
    Behavior on bearing {
        RotationAnimation {
            direction: RotationAnimation.Shortest
            duration: map.ready ? 500 : 0
            easing.type: Easing.Linear
        }
    }

    // new sub-items following the same principles
    Item {
        id: subitem
    }

    // connections
    Connections {
    }

    // signal handlers
    Component.onCompleted: init()
    onActivated: doSomething()

    // functions
    function a() {
        return 10;
    }
}
